Windows 10 failed install, failed to revert to previous OS

Thank you for the reply.

The PC is an Acer all in one but I'm unable to remember/locate the model.

Prior to attempting the upgrade we did unplug all devices except for the mouse and keyboard. We had Avast installed for antivirus but we made sure that we disabled this before upgrading.

We get no error messages, but when trying various ways to try and fix the issue I did receive a message saying that OS Loader could not be found

Hi Leon,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing currently.

I would appreciate if you can provide us the following information to help us understand the issue better.

• What is the make and model of the computer?

• Do you have any third party security program installed on the PC?

• Do you get any error code or error messages?

As of now, I suggest you to disconnect all the external devices (printers, scanner, USB (universal serial bus) drives, etc...) Except mouse and the keyboard and then boot up.

If this corrects the issue then add the devices back one at a time until you discover the piece of hardware causing the issue.

Please get back to us with a reply so that we can assist you further.

Hello Yuniel, *Smile

I had this issue on my laptop, and had to do a repair install (in-place upgrade) using the latest version/build to get to finally update afterwards.

thanks brink for the reply , i just want wait to repair installation of windows i just format this PC 2 weeks ago

i looking for clear the windows update history and i found this in microsoft website

Method 2: Steps to erase Windows Update history
Note:Erasing the windows update history will just remove the entries of the updates and not really the updates itself.
a. Go to menu Start> All Programs> Accessories. Right click on the "command prompt" and select "Run as Administrator".
b. Copy/paste the below command:
c. net stop wuauserv
d. And select OK.
e. Wait until confirmation that the service is stopped.
f. To delete the file, copy the following command in the command prompt:
g. del %systemroot%\SoftwareDistribution\DataStore\Logs\edb.log
h. You can also delete it manually by going to the location in windows explorer.
i. you can restart the service with this command:
j. net start wuauserv

i do it , but the problem brink when i type the command net stop .......... say my windows update no even started look like is already stop ? , then i copy net start........ and say is started so this confused me why is stop if i never stop it , well i restart my PC and copy command again net stop and say the same windows update no started just saying is already stop , so everytime i restart my PC or from shutdown my windows update stop ?? look like maybe this the reason why my automaetically windows update fail 4 time and work only manual

 

I can understand that. If you're worried about losing everything, then you don't have to. You won't lose anything doing a repair install.

If you like, you could use the .bat file in the tutorial below to make resetting Windows Update easy.
